Tech in 24 hours on Instagram: "The "underwater ghost" jellyfish robot by Northwestern Polytechnical University is a 12 cm wide, 56-gram transparent device that moves like a real jellyfish using electrohydraulic muscles. It uses just 28.5 milliwatts of power and has a built-in AI camera for underwater object detection. Designed for silent, low-disturbance long-term monitoring, it suits deep-sea surveillance, ecological observation, and underwater facility inspection. Join Telegram(link in bio) t

Tech in A Day on Instagram: "Chinese scientists have developed a lifelike robotic jellyfish with a transparent body and tentacles, nicknamed the "underwater ghost." The robot uses electro-hydraulic muscle actuators and hydrogel electrode materials to mimic jellyfish propulsion, consuming low power. Equipped with a camera and AI chip, it can identify underwater objects and potentially be used for surveillance and exploration. The robot is designed for long-range monitoring due to its low power co
